Anything below 100%=10/10 is seen as a failure!

I took my Audi A4 for service to \Audi\" Hatfield on 17 Feb where I was assisted by Ben. I requested that on top of the service they check everything that needed to be fixed and specify there was a water lick. Ben gave me a list of things that needed to be changed & we agreed on what needed urgent attention. He called me again to say they are finished and it is R7752, I asked him about the lick he said there was nothing but I insisted he checks because I saw there was a lick. Suddenly, he found the lick and costed R14000. Money was not an issue only wanted my car fixed. It took 3 days to complete the job. After I had paid Ben told me that \"AUDI\" JHB branched did not service the car properly on its last service it is still going to give me problems. Except the lick the performance was good but after service it was worse. I reported and Kevin instructed me to take it to Audi PMB where the manager confirmed Hatfield was at fault and he advised me to contact Audi SA. I spoke to Lavena who put down the phone on me because she couldn't answer my questions. She said AUDI cant help me any further. They couldnt even get the amount on the invoice right. Where do I take the AUDI car now, VW?"
